Compare the Physiological Parameters and Behavioural Responses among Mixed Fed Versus Formula Fed Preterm Babies

Preterm birth is the most common causes of death among infants in worldwide. Prematurity causes the largest number of admissions to the Neonatal Intensive Care Unit (NICU). And appropriate nutrition is essential for the growth and development of preterm infants.

The aim of the study was to compare the physiological parameters and behavioural responses among mixed fed versus formula fed preterm babies admitted in AIMS, Kochi.

A descriptive approach was taken, sample were selected by convenience sampling technique, data had been collected by semi structured questionnaires and used record sheet and FENTON Growth chart to assess the physiological parameters and behavioural responses of the preterm baby.

Weight gain, length, head circumference in mixed fed preterm babies were highly significant compared to formula fed preterm babies. Body temperature was very highly significant between two groups. The heart rate and mean respiratory rates were progressively higher in formula fed preterm babies than mixed fed preterm babies. Blood pressure was very highly significant between two groups and was higher than formula fed preterm babies. In majority, the oxygen saturation level was decreased in formula fed preterm babies than mixed fed preterm babies. Sucking reflex was absent among 74.3% of formula fed preterm babies and it was statistically significant. Rooting reflex was also absent in 42.9% of formula fed preterm babies.

The study findings revealed that the mixed feeding is very effective and beneficial to gain weight, height, to maintain body temperature, heart rate, respiratory rate and oxygen saturation compared to formula feeding.
